WebLong-term drift, and the required tests connected with it, are specified in the EN 61298 standard. The long-term stability is defined in DIN 16086. How do long-term drift and long-term stability differ? With long-term drift, in accordance with EN 61298-2, chapter 7.2, a pressure value of 90 % of the measuring span must be maintained for 30 days. WebDec 22, 2015 · OTDR is used to test the performance of newly installed fiber links and detect problems that may exist in them. Its purpose is to detect, locate, and measure elements at any location on a fiber optic link. OTDR works like radar—it sends pulse down the fiber and looks for a return signal, creating a display called a “trace”or “signature ...
